Abstract: A class of nonlinear singularly perturbed initial-boundary value problem with ultra parabolic equation is considered. Firstly, the comparison theorem is introduced for corresponding problem. Then the formally asymptotic solution is constructed by using the singular perturbation method. Finally, using the comparison theorem, the existence and its asymptotic behavior of generalized solution for the problem are proved.
Key words: ultra parabolic equation    asymptotic behavior    comparison theorem
